Gantry crane lifting beam using methods and precautions

Mobile crane, the  overhead bridge crane  hook lifting beam with rings connected, when starting to rise to the right height, to see whether the level of lifting beam, hanging chain kinks.
Then move the main beam to the top of the hanging objects, with the connection rigging and hanging objects connected, then slowly improve crane.
Hanging test Balance:  steel crane  increased, the main Liang Pingheng should be less than 1 °, with the naked eye of the load beam is in equilibrium, when fully in equilibrium, can be lifted.
Load test crane
Hanging load test preparation process is the final process of the overall operation of the last part of the entire process,hoist gantry crane the load should be gradually increased, when just off the ground, stop upgrading, the force was observed as a whole, and then slowly release the load, if not abnormal, be normal lifting.
